Filed: 1970-05-26
Abstract: 1316609 Continuous casting VEREINIGTE OSTERREICHISCHE EISEN - UND STAHLWERKE AG 26 May 1970 [30 May 1969] 25267/70 Heading B3F [Also in Divisions B8 and F2] In a curved guide apron for a cast strand, guide rolls 28 are supported by pivoted links 30 from curved longitudinal carriers (1-8 and 1<SP>1</SP>-8<SP>1</SP> across the width of the curve as shown, but there need be only two at each of the inner and outer sides of the curve) in a framework comprising spaced mounting brackets 15, 16 (-21), 151, 161 (-21<SP>1</SP>) connected together by elements 22, 22<SP>1</SP> to form rigid curved supports interconnected by struts 23, the spacing between the curved inner and outer carrier sets being adjustable for different strand depths and, to establish the parallelism of the curved carrier sets after the space adjustment, at least one of the sets is elastically deformed by means, e.g. hydraulic cylinders 38 (39), which connect the ends of the set to the framework. There may be several roll-carriers 3-6, 3<SP>1</SP>-6<SP>1</SP> and links 3 across the width of the strand path for wide slabs as shown, but a small plant might have only two carriers at each side of the curve. There may be resilient links (35) (see Division F2). The curved roll-carriers 1-8 or 1<SP>1</SP>-8<SP>1</SP> at each side of the path curve are joined at their ends by cross-members 9, 10 or 91, 101. As shown, the carriers 1<SP>1</SP>-8<SP>1</SP> are releasably connected to the supports 15<SP>1</SP>, 16<SP>1</SP> (-21<SP>1</SP>) by bolts 13<SP>1</SP>, but the carriers 1-8 are connected to the supports 15, 16 (-21) to be adjustable towards or away from the strand path by exchanging spacers 25, 26. Alternatively, the outer-side carriers or both sets of carriers may be adjustable. To change the spacers 25, 26 on bolts 13 for ones of different size, wedge fasteners 14 are loosened and then the carriers are pulled tightly to the supports 15-21 so that there is elastic deformation of the carriers 1-8. The latter carry slides 24 which move in slots 11a (extending parallel to the path) in lugs 11 on the carriers and the slides are connected to the brackets 15, 16 (-21) by bolts 12 and the bolts 13 with their wedge fastenings 14. The curved framework is releasably fastened to the pouring platform or foundation of a continuous casting plant. It may be displaced by means of wheels (31, 32) and may be lifted by a crane, using a lug (33), for exchange for another curved supporting and guiding construction. Cooling water jets are arranged at or within the framework.

Patent GB-1119972-A (GB)
Title: Filtration process
IPC: C02F1/44
Filed: 1965-07-19
Abstract: In the removal of solutes from solutions by reverse osmosis the membrane assembly is rotated so as to apply a centripetal acceleration greater than that of gravity away from the membrane, thereby preventing the build-up of excessive concentrations of solute next to the membrane.  The membrane supports may be circular or polygonal in cross-section and they may be either generally cylindrical or frustoconical in elevation.  Different membrane systems are also described in which solutions are fed to membranes in series or in parallel.  Particular embodiments of suitable apparatus are described in the original specification. The process may be applied to the recovery of water from sea water or sewage.  From time to time the membrane may require to be cleared of solid material or crystals.  This may be done by back-flushing by allowing pressure to rise on the output side of the membrane, by shutting off the output and introducing high pressure water on the output side of the membrane, but most expeditiously by the "water hasser" effect by suddenly and very rapidly closing the output line.

Title: Improvements in combined automatic couplings and buffers for railway vehicles and the like
IPC: B61G3/16
Filed: 1924-10-30
Abstract: 246,577. Thomas, J., and Mitchell, J. Oct. 30, 1924. Couplings, automatic; couplings, automatic convertible to non-automatic. -A central buffer coupling A is centralized relatively to an opposing coupling member in both a horizontal and a vertical plane by curved or inclined surfaces D', D<2> and B', B<2> respectively, the coupling members being rotated in opposite directions by the surfaces B', B<2> of the hooks engaging the corresponding hook surfaces on the opposing coupler until the noses of the hooks are in a position to engage, whereupon the forwardly projecting portions of the hooks engage inclined surfaces E<1>, E<2> 2 inside the heads to rotate the coupling heads in the opposite direction to effect a close coupling of the hooks. The couplings are disconnected by inserting the pointed end of a lever H between the noses of two engaged hooks by means of a side lever K<1>, Fig. 12, operated from the side of the vehicle. The side lever has an arm provided with a projection K which engages a stud on a pivoted cam M adapted to rotate an arm F on the pivot of the lever H. The side lever K<1> is pivoted on the shank of the coupler on which it has a lost motion so that the lever may be turned to insert the pointed end of the lever H between the hooks when the couplings are pressing hard against one another which enables the hooks to slide off one another when the vehicles draw apart. A draw hook N or a stud may be provided inside the head for connection with a link coupling, or a pin which passes through the head may be provided. A horizontal or inclined slot may be provided in the head for the reception of the non-automatic coupling link when automatic coupling is resorted to. The, inclined surfaces E<1>, E<2> may be placed near the buffing flange of the coupling. A pin V secures the lever K<1> in such a position that the lever H screens the coupling hook to prevent automatic coupling during shunting operations.

Title: Improvements in machines and appliances for shearing metal plates and the like
IPC: B23D19/08
Filed: 1933-09-19
Abstract: 424,656. Shearing. BENNIE, H. O., and ORR, R. W., Clyde Engine Works, Drumoyne Road, Govan, Glasgow. Sept. 19, 1933, No. 25860. [Class 83 (iv)] In a shearing-machine the shearing-head is mounted on a vertical pivot to allow of making curved cuts. Rotary cutters 9, 10 are rotated from a gear 15 driven by an electromotor and mounted on a head 5 pivoted on a shaft 16 on a bogie 6. The head is swung by rotation of a hand wheel 21 and gear 20 engaging a fixed arcuate rack 19. The bogie wheels 7 are driven by the shaft 16 through to a slipping clutch on a shaft 34 from the gear 15. The work is clamped to a table 1 on wheels 3. A track 37 on the table houses a bowl 39 on screws 40 engaging half nuts 43 and rotated by splined woven wheels 44 from a hand wheel 45. The nuts 43 may be disengaged from the screws on depression of a pedal 51. In cutting a straight edge a gauge wire 59 is positioned over the cutting line by adjusting handwheel 45 and the cutters are rotated and travelled by the gear 15. In cutting a curve the machine is slewed by manipulation of hand wheel 21 to maintain the wire 59 tangent to the curve. In modifications the cutters may be freely mounted and may be pivoted or reciprocated. The work or the cutters may be stationary or movable. In a further modification a point on the plate is constrained to move in a straight line and is supported on castors to allow of the plate slewing in cutting or curved edge, Fig. 5 (not shown).

Title: Car coupler
IPC: B61G3/06
Filed: 1969-05-21
Abstract: 1,212,970. Automatic railway couplings. MIDLAND-ROSS CORP. 21 May, 1969 [22 May, 1968; 27 Sept., 1968], No. 25867/69. Heading B7T. A "Janneg" type railway car coupler comprising a knuckle 11 pivotable between a closed and open position and a conventional lock 13 operable in known manner to lock the knuckle in its closed position, and there being provided a manually operable released mechanism for releasing the lock, and an automatically operable release mechanism for releasing the lock when the coupler is disengaged from a mating coupler, said automatic mechanism being held in an inoperative position by said mating coupler when the couplers are in coupled relationship, and there being a spring-loaded lever 42 pivotally mounted in the coupler, the lever being movable under the action of the spring to actuate the manually operable release mechanism to release the lock when the coupler is disengaged from the mating coupler. The coupler operates as follows:-during coupling with a mating coupler a plunger 45 is caused to move into the coupler compressing a spring 60a, 60b. For uncoupling it is assumed that the knuckle of the mating coupler is unlocked manually using rod 28. As the couplers move apart the knuckle noses will move into contact and plunger 45 of the coupler move forward under the action of spring 60. Thereafter the knuckle of the mating coupler will be fully opened whilst that of the coupler is still closed. Further movement apart will cause plunger 45 to actuate an arm (42b) of lever 42 which in turn actuates a rotor lever arm 55 until the lock has been raised. A knuckle opening spring (70) then swings knuckle 11 to the open position. In a modification, Fig. 22, the coupler operates as follows:-during coupling with a mating coupler the plunger 145 is moved into the coupler and a spring 154 compressed. It being assumed that the lock of the mating coupler is manually unlocked and its knuckle is free to pivot towards an open position, movement apart of the couplers causes contact of the knuckle noses and plunger 145 moves forward under the action of spring 154. Further separation will fully open the knuckle of the mating coupler and as plunger 145 continues to move out, lever arm 142a acting against a cam arm 180 actuates a rotor lever 122 until the lock has been raised to the unlocked position. Complete separation of the couplers causes arm 142b through the force of spring 154 acting against rotor member 174, to actuate rotor lever 122 the amount necessary to fully open knuckle 111.
